Eastbound lanes on Interstate 10 between Kenner and LaPlace reopened shortly after 10 p.m. after being closed for several hours, but westbound lanes remained closed Sunday night, according to Louisiana State Police. Traffic was totally shut down while police negotiatied with a man who had a gun and apparently threatened to kill himself.

In the westbound direction, traffic is being diverted off the highway at the Williams Boulevard exit. In the eastbound direction traveling from LaPlace, traffic was diverted just before the highway's interchange with Interstate 55.

State Police spokeswoman Melissa Matey said the armed man jumped from the elevated roadway near the Bonnet Carre Spillway. He was rescued from the water by one of three St. Charles Parish Sheriff's Office boats and was placed in custody. He apparently was not seriously injured.
